Installation-Network Structure
To ensure LaneCat work well and realize network monitoring/management,
pelease read instructions below.
First, we need to known how does shared hub and switch work.
If you use shared hubs to connect computers, computer A need to
contact with other computers in LAN, data packages that computer
A sent will be copied and sent to all computers in LAN. In other
words, any computer in the LAN can capture all data packages that
other computers sent. This is the precondition of network content
control program. So in a shared environment,
content control program can be installed on any computer in the
LAN and capture all of network traffic.
The most differences between shared hub and switch is that switch
won't send data packages to all computers, but only sends data packages
to one port that destination computer precisely. In this case other
computers can't capture data packages. If you want to dipose monitor
software in this kind of network, you have to install monitor program
on the network export port.
LaneCat is a kind of network bypassing monitoring software. In
principle, it can be installed on any computer in LAN. But different
LAN has different network structures, network devices, and different
topologies, so if user wants to monitor all computers in the LAN,
user should install the LaneCat engine on the computer which connected
to the network main export port. If the network main export port
is router or firewall, the LaneCat engine should be installed in
the same network segment, for example: Shared hub's port, switches
administrable management port.
Our suggestions:
According to the volume of the data flow, choose a computer as a
monitor server to monitor bypassing. This installation won't affect
the network speed. If the computer is good enough, it also can be
used for other works.
According to the network topology, LaneCat Engine can be installed
in following methods:
1. If the LAN connects to the Internet by Proxy Server/NAT, the
LaneCat Engine should be installed on the computer that Proxy Server
located and choose the intranet NIC as monitor NIC；
2. If the LAN connect to the Internet by shared hub, the LaneCat
Engine can be installed on any computer in the LAN:
3. If the LAN connect to the Internet by switch and use software
to share network, LaneCat.Engine should be installed on devices
that connected to Internet, such as Gateway/Proxy/Firewall. If the
switch has mirror port, please set that port as gateway locates,
and connect that mirror port to the computer LaneCat Engine locates:
4. If the switch has LAN manage port itself, these ports can be
used to run SNMP manage software. User can connect the computer
that LaneCat located to these ports. If user need to run other manage
software, user can connect a shared hub to these port. User can
run other network manage programs as well at the same time；
5. If the LAN connect to the Internet by router
and switch, but the switch is low-end and doesn't has mirror manage
function, user should add a shared hub between router and switch,
LaneCat Engine should install on the computer connected to this
shared hub. That is to say, user should connect the gateway devices,
intranet switch and the computer that LaneCat Engine located to
the shared hub. Because shared hub is a kind of share device, LaneCat
can get data it needs. This method is also suitable for situation
of not suitable install port or need to monitor the web/email-sever:
